To return to south Alabama. During the years 1861 and 1862 the defences of Mobile were made almost impregnable. They were commanded in turn by Generals Withers, Bragg, Forney, Buckner, and Maury. The port was blockaded in 1861, but no attacks were made on the defences until August, 1864, when 15,000 men were landed to besiege Fort Gaines. Eighteen war vessels under Farragut passed the forts into the bay and there fought the fiercest naval battle of the war. Admiral Buchanan commanded the Confederate fleet of four vessels--the _Morgan_, the _Selma_, the _Gaines_, and the _Tennessee_.[87] The _Tecumseh_ was sunk by a torpedo in the bay, and Farragut had left 17 vessels, 199 guns, and 700 men against the Confederates' 22 guns and 450 men. The three smaller Confederate vessels, after desperate fighting, were riddled with shot; one was captured, one beached, and one withdrew to the shelter of the forts. The _Tennessee_ was left, 1 against 17, 6 guns against 200. After four hours' cannonade from nearly 200 guns, her smoke-stack and steering gear shot away, her commander (Admiral Buchanan) wounded, one hour after her last gun had been disabled, the _Tennessee_ surrendered. The Federals lost 52 killed, and 17 wounded, besides 120 lost on the _Tecumseh_. The _Tennessee_ lost only 2 killed and 9 wounded, the _Selma_ 8 killed and 17 wounded, the _Gaines_ about the same.[88] The fleet now turned its attention to the forts. Fort Gaines surrendered at once; Fort Morgan held out. A siege train of 41 guns was placed in position and on August 22 these and the 200 guns of the fleet opened fire. The fort was unable to return the fire of the fleet, and the sharpshooters of the enemy soon prevented the use of guns against the shore batteries of the Federals. The firing was furious; every shell seemed to take effect; fire broke out, and the garrison threw 90,000 pounds of powder into cisterns to prevent explosion; the defending force was decimated; the interior of the fort was a mass of smouldering ruins; there was not a place five feet square not struck by shells; many of the guns were dismounted. For twenty-four hours the bombardment continued, the garrison not being able to return the fire of the besiegers, yet the enemy reported that the garrison was not "moved by any weak fears." On the morning of August 23, 1864, the fort was surrendered.[89] Though the outer defences had fallen, the city could not be taken. The inner defences were strengthened, and were manned with "reserves,"--boys and old men, fourteen to sixteen, and forty-five to sixty years of age.
